After-such operation it is necessary to completely deflate the tubes forfurther inspection and boxing. My invention relates to a device fordeflating the tubes and has for its object to provide a device of thatcharacter which will deflate a substantial number of tubes at one timeand so arranged as to facilitate the handling of the tubes to permit ofa substantially continuous operation.

In the accompanyingdrawings which illusmy invention,

Figure 1 is a side elevation,

Figure 2 is a plan view and Figure 3 is a detail showing the manner oisupporting the tubes during the deflating operation.

Referring substantially rectangular frame to which are The upon whichwheels 6 is adapted to be reciprocatcd. Carriage cooperate respectivelywith ens 2 and 3. Carriage 5 is reciprocated by means of an air cylinder11, secured to uprights 12, forming part of frame 1, the piston rod 13of the air cylinder is secured as at 1 to the carriage. The airconnections and control valves for the air cylinder may of anyconventional form and have been omitted from the drawings.

A substantially continuous operation is thus obtained with aminimum handling of the tubes.
